Things to take care of before putting in a pullout motor?

[71maroesteban]

Should I replace the timing chain, tensioner, oil pump and water pump before putting the motor into my car? The engine had 74k on the clock and was well maintained it's. It was out of my uncles car so he had the service records, just want to know what to take care of to ensure the engine will last me at least 80k thanks

I think that is a bit much but is within reason. I would at least do the front and rear main seals, check the freeze plugs for corrosion, give it a good look over for any leaks and also detail or paint the engine if you want to. If you have any plans for the motor down the road might want to do them now, specifically a cam shaft

If you're going through the trouble of taking it the oil pump and timing chain might s week throw a cam in there while you're at it. I think the water pump can wait since its not an internal part and can be easily replaced. Do the oil pan gasket if it does any signs of leaking

Katech rod bolt are also a great upgrade, depending on the year of the engine.

Do the oil pan gasket if it does any signs of leaking the oil pan is being swapped with an ls1 pan so that'll be taken care of. I was thinking of doing a cam swap but don't want to go in that deep the engine is on a stand and my main concern is putting it in and it not have oil pressure and blowing up, happened to my last motor so it's something of scared of

Speaking of oil pressure, if you are swapping pans you will most likely be swapping pickup tubes. Make sure you have the correct o-ring on the pickup where it connects to the pump. My bottom end gasket set came with 2 different ones, and I happened to install the wrong one. It had very low oil pressure at idle. I shut it down, finally managed to drop the pan without pulling the engine, and got the correct o-ring on the pickup tube. It now has great oil pressure all the way around.

As for not having oil pressure after a cam swap. I wouldn't worry about that. The oil pump is in the front of the engine and is driven by the crank. As was mentioned above, if you are changing you timing chain you will be pulling the oil pump to do it. No reason to not put a cam in at that time. Just remember a bigger cam will almost always mean a valve spring change as well.
